Cool PC-5's IN STOCK & READY to SHIP

DYNOTECH Jim's post on H.C.S. Friday:

Still waiting for cold weather for further leanout, but right now we're using our 50 degree F 2010 D8 maps for stock, SLP, DynoPort, BMP exhaust which will be preloaded into the PCV before shipping.

old PCIII maps will not download directly into PCVs---there is an extra step in throttle position which can be manually interpolated, and I've done that for the excellent PCIII D7 maps we used last year and am doing that right now with the maps we created with Casey's 2010 spec sled. Updates and new maps will be posted on my website, easy download.

PCVs are $369 w/ free shipping in November, premapped
Autotuner kit for fine tuning and self mapping $250 additional includes Bosch wide band O2 sensor, weld on bung, and threaded plug so you can remove the O2 sensor after tuning is done (a few hours).

Polaris dealers please call for information.

For orders/ questions/ tech support: 585-993-2777



The idea is to allow the autotune to tweak your PCV map to the desired A/F ratio for each RPM and throttle position, then remove it and plug the O2 sensor bung and you're set. It is feasible to leave the autotune on permanently and let it do miniscule adjustments on the fly, but that's surely not necessary once you have achieved the desired map.

Guys who are running basic setups, ie stock engines with various pipes etc wont need autotune because we'll create very good maps from the dyno and you can download those maps and be all set. We'll be doing only PCV maps this season, but PCIII owners can easily adapt V maps by typing them into their PCIIIs, in two minutes.

But if I was running a Dragon at higher altitudes I would opt for an autotune. We had lots of high altitude D8 PCIII users with our DTR flatland tuned maps, and were happy. But perhaps the autotune would make it even better, optimizing A/F ratio regardless of how the factory ECU compensates for altitude.

Mountain riders cover a large variation of temp, alt, snow conditions, I wonder if leaving the auto tune on would help maximize maps over these conditions. If one was to ride that same area with similar conditions I could see unplugging it. 250$ for a custom map seems a bit steep unless a few peeps where going to group buy it, each take a turn in making a custom map?

Good to hear someone is getting this incorporated into the sleds. Any news of T-nytros application?

it's $250 for the AUTOTUNE product built by Dynojet (Las Vegas) sold by Dynotech (New York) The Autotune includes the control box, O-2 sensor, weld bung , etc.

Nobody's selling/charging for maps here.

Has anyone applied the PC's to a turbo application? I'm assuming they have since they offer an analog input for a boost reference. Also is that function available on the CFI versions of the PCV?

The autotune builds the map based on set A/F readings. So it ends up being 250$ for auto tune to build the perfect map. I am familar with the autotune add on and its components but once it builds you a map it becomes of minimal advantage esp if the 02 sensor starts to crap out and it adds more fuel and wrecks the map.

Its a great idea maybe just overpriced?

Is this why they say to remove the O2 sensor and put the plug in after it autotunes? Just curious.

Overpriced, a POLARIS 3211115 belt for $160+ is overpriced, I.M.O.

The Autotune can be kept ON all the time for constant fine tuning, especially advantageous to mountain riders who ride at various altitudes/conditions within the same day so that the system is constantly learning and fine tuning.

Failure of the O-2 sensor does NOT wreck the map, the system reverts back to the previous failsafe map that you have stored in the system's memory.

It took only (3) pulls on the dyno for the Dynojet Autotune system to trim fuel and get the fuel curve close to "spot on", so even with an O-2 sensor failure out on the trail you can carry a spare O-2 sensor, replace it and be "spot on" again in less time than it takes to change a belt!

These O-2 sensors should have no problem lasting the entire season, and @ $70.00 each, consider it a maintenance item and replace it once a season.

Correct, for those that are nervous about the O-2 going bad, they're saying that after only 3 dyno pulls the Autotune/Dynojet system has the engine pretty much "spot-on"

They go on to say that it is feasible to leave the Autotune on all the time, although the benefits may be slight.

Let's not forget that the FST/WEBER (yeah 4-stroke, I know) has a fully closed loop system that's ON all the time!

It's not a right or wrong thing here, just personal preference on a cost/value/comfort level, that's all.

The way I see it, Autotune is the future and it's here today. Anybody running the Autotune (whether on all the time or just for a little of the time) will be far ahead of the competition.

^^^ Good points. I signed up for DTR today. There's some good info out there and the PC5 sounds like it is worth the price.
